The following series is pulled from a presentation I gave to a group of beauty bloggers hosted by L'Oreal in New York. Most of the presentation is geared toward how to make a blog more search engine and user-friendly, however I will expand many of the concepts here to include tips and strategies for sites selling products or services across all industries.

Link Analysis Progression

Link Anatomy

I said in my last post that each link is essentially a vote for the page that's being linked to. That, essentially, was the original link analysis factors. Things have come a long way since then. Today's link analysis factors are far more complex.

Over the years what gets analyzed as part of the link has changed in order to provide better search results to web users.

The search engines started out looking at sheer link volume. He who gets the most links wins. This created link farms, link trades, link pages and so on. Before Google changed the game in link analysis people did everythign they could to create mad quantities of links to their site. Relevance of the linking page to the linked content didn't matter. While sheer link quantity continues to play a role, it is no longer the only factor in link analysis.

Then Google came a long and started analyzing link text. The words in the link started to matter. The words spoke about the page it was linking to and therefore when the words match up with the text on the page the more relevant your page became for those keywords.

Next, search engines started looking at the quality of each link. Does it come from a low authority website or a high authority website? The higher the site's authority linking out the more link value was passed.

Link age became a factor as it was assumed that the longer a link stayed in place the more "serious" the linker was about the site. If the links came and went then that might say somethign about the quality of the site being linked to, or if the link was an ad purchased under the radar.

As link buying became more and more prominent, the search engines started fighting back. It's impossible for the search engines to determine with 100% accuracy whether a link was purchased or not but there are some signals that they have learned to detect.

The Anatomy of a Link

Link Anatomy

There is more to a link that meets the eye. As the progression of link analysis has changed, that means we need to pay attention to our links in order to make sure that we are getting the most value out of each. Lets break down the link into its core components as relevant to the search engines.

Anchor Text: As noted earlier link text factors pretty heavily in the search engine rankings. Any clues the search engines can get about the content of the page from external sources weighs heavily. It not only tells them what the page is about, but that someone else found it as a valuable resource for what it is. That last part is important. Linking to a site is one thing. Linking to a site giving your readers context to what they'll find on that site is another thing altogether.

Links you give (and receive) should be keyword rich. Instead of linking out using the name of the website you are linking to, use keywords relevant to that site. Don't say "you can find a good used Honda Accord at Joe's Dealership." Instead, say "you can find a good used Honda Accord at Joe's Dealership."

Where it Appears: Where the link appears on the page tells the search engines a great deal about the link itself. Search engines try to determine the value of the link by its placement on the page. Links in navigation are weighted one way, editorial links are considered more relevant and links in ad spaces are generally ignored.

Editorial links (those linked in the the midst of the page's primary content) are deemed most valuable. These are generally links that are there not because they were purchased (though clearly that can be manipulated) but because the writer of the content finds it relevant to the readers.

Type of Link: There are a lot of different types of links and each carry their own weight. Many people will tell you that reciprocal links are worthless, but that's not entirely true. Context matters a great deal. The same is true for whether the link is a one-way (non-reciprocated) link pointed to the site but not returned. Known purchased links have the least value (none), but can still be useful for driving traffic and getting an audience which can also produce natural links.

Link Style: Text vs. Images. Linking actual text (words) gives the search engines more information as to what the destination site is about. It adds to the page's keyword focus from an external site. Image links don't do that as well. Images can use the ALT text which can be factored in but likely aren't weighted with the same value as a pure text link.

Link Age: How old a link is and how long it's been in place can effect the overall value of that link. In general terms the longer the link remains in place the more power it sends to the linked page. This isn't true in all cases, for example I believe blog links give out some immediate value that then fades back into the normal aging process after a few months. News links likely fade over time rather than build strength. But with these (and possibly a few other) exceptions, the link gains value over time.

Linking Site: The site that links out plays a strong role in the value of the link itself. The higher authority the linking site is, the more link value is passed. The page the link is on is also considered. A low authority page on a high-authority site may not have as much value as a lower authority site linking out from its home page, or the reverse may be true.. The topic of the page, how relevant it is to the topic site, can also be factored into how much relevance and weight the link sends out.

There are other factors as well, and I'm sure Google is always looking at ways to improve their link analysis algorithms. Links from Twitter and Facebook profiles can factor in as can links from other social media sites.

Whether you're buying a link, asking for one, or looking for exposure in social circles, the key is to get as many quality links from quality sites as possible.

Stoney, I've been reading your posts here for almost a year I think....and I'm still very impressed and wanted to say so publicly. I'm an SEO practitioner up here in Canada, and while Canada itself is definitely behind the curve for just about all SEO factors (ie behind the US I mean) what I've read in your posts is both 'futuristic' and spot-on! Congrats on a great series too, your SEO 101 is very muchly appreciated too! I send my clients your URLs for them to read up on why we do certain SEO tactics, and you explain very very well! Thanks Stoney, and I can't wait for more posts!

So, I guess I'm wondering if reciprocal link pages are a thing of the past? I'm referring to links that are from closely related topics to the main site?

@Carolyn - yes, I would say reciprocal link pages are dead. Even if closely related. There is nothing wring with linking out to quality resources but pages build specifically for reciprocating links are pretty much valueless to the search engines.

I'd tend to agree with you on the reciprocated links page. But that said, sometimes these are a useful resource, so no harm in leaving it there - just don't expect it to offer much in terms of SEO.

I am pretty sure that nofollow links are important to some degree. This may seem misleading, but I'm almost certain that the more nofollow links you have, the more weight is given to the higher quality links. My thinking behind this one is that the back link profile just looks so much more natural.

@Robert - not sure I agree with that. It wold seem that nofollow links are the exact opposite of natural.

@Stoney, I hear where you are coming from, but wouldn't a site that had no nofollow links seem just a little suspicious? That's what I'm getting at. A natural back link profile would include various forms of links, text, image, no follow...etc.

After all, if you've offered someone a fantastic bit of advice on a blog linking back to your site, it'll most likely be nofollowed. If someone else links to your site in discussion it'll be nofollowed and so on.

Don't get me wrong, I not saying this directly help you, but rather the absence will raise a few flags.

@Robert - I dunno, I never pimp myself on blogs so if I'm getting no follows then they truly ARE natural. I think its one of those things that they'll either come naturally or they won't and either way, it IS natural.

@Stoney, Fair enough ;)

Although I've had a few editorial nofollows from large news sites (they're terrified of passing any link love), so imagine those while not carrying any link weight still generated some traffic.

Generally I'll take any link... giving, I'm a little more reserved.

@Robert - I'll agree with that wholeheartedly.

Nice articles. However, when I saw the title for this one, I thought it was going to talk about the site structure/architecture, use of no-follow strategically to flow google-juice where it is most effective, etc. Similar to some of the work that Andy Beard has spoken about. I would like to see your take on those concepts.

What exactly do you mean when you say "links in ad spaces are generally ignored"? How does one define an ad space? Is it a predetermined location on a page?

Search engines try to sniff out areas of the page that contain ads. It's different for every site, but they are certain clues that might make them obvious.
